Been running my laser thru USB. As my computer is in basement and I'm too cheap and lazy to run cable from my router up into attic and across and down into my basement, I've been using a wifi extender in the basement. And wifi dongle for the wifi connection at the computer. But USB connection is slow. Way slow as compared to Ethernet. But windows 10........ If I connect the lase to the Ethernet, either with or without a switch, win10 randomly cuts off internet. Thinks Ethernet should have internet, when it plainly doesn't.
I finally searched around and found I could change setting to make computer always look for internet thru wifi and never at Ethernet. But it sure wasn't easy! Should be easy, but not! But internet works and so does laser! Now i cna connect fiber through USB or Ethernet ( if that is option).
